We are a group of sub system providers to the maritime industry, all developing high quality products and enabling our customers through the green transition in the maritime industry
Our brands are part of three divisions
Propulsion management
Offers vibration compensators, cylinder lubrication systems and piston rod stuffing boxes. We cooperate with engine manufacturers and shipping companies to optimise main engine operations and support the important task of utilising new environmentally friendly fuel types.
Water & Waste management
Includes incineration plants and biological water purifying plants, securing that waste water is purified before discharge while solid waste and oil sludge is incinerated at high temperatures to reduce SOx and NOx emissions.
Tank management
Provides PV valves and protects tank vessels against unintended overpressure or vacuum while simultaneously protecting against fire risk and ensuring that emissions from the cargo is kept to a minimum in accordance with IMO standards.
One group, six leading brands
Incineration of waste and oil sludge, eliminating the need for discharging to shore while reducing emissions from incineration.
Biologically cleaning of grey and black waste water before it is discharged.
Compensators that eliminate vibrations at the source, reducing cost, improving comfort, and cutting fuel spend.
Leading global provider of cylinder lubrication systems for two-stroke marine engines.
Piston rod stuffing boxes for two-stroke engines continuously improved to live up to new fuel types entering the market.
Valves and venting equipment reducing emissions from cargo while keeping vessels, equipment and crews safe every day.
Our vision is to make vessels a greener and safer place to work
